Betta fish marble gene.

Well she sent in some photos of her betta fish and it became immediately obvious that she has a marble betta. The black lace betta is a dark colored fish that rarely approaches the depth and intensity of the melano black 18. A dna sequence that can change its position within the genome as a result marble bettas often have splotches of pigment or areas without pigment all over their body and fins. If the solid colored parent betta carries the marble gene the percentage of marbled fry increases.

These patterns are not usually defined by colors and multiple patterns can appear on a fish making for a large range of possibilities. Displays of neurological condition. Patterns that appear on bettas are the result of gene s that modify the way pigment appears on the fish. It is a partially recessive genetic so if you have a betta with the marbling gene and you breed it to a betta with no marbling genetics you might get a few marbled fry.

A result of the. Marble is used to describe a type of betta fish by its physical blotchy appearance but more importantly by the special genes they have called jumping genes or transposons as they are now called. In fact marbling is pretty common. A lot of people in the fish community seem to believe this is the origin of marbling but keep in mind 40 of the human genome are transposons and we don t really marble.

Most black lace fish display too much iridescence in body and fins to be competitive in the black class and are instead shown into the dark bicolor class. But they all carry the gene. Most black lace fish we see today come out of marble strains. You are bound to get at the least a quarter marbled fry.

Now let s say you breed 2 marbled betta. Because the marble gene is a transposon its color is unstable and often marble bettas will develop more or less color throughout their entire lives.
